Renji's Bankai is smaller now that it has powered up... OBVIOUSLY...
Why Kubo, why do you keep finding bullsh*t reasons to blur your own boundries???
Size doesn't really matter... at least not that much.
Remember some chapter/episode when Ichigo's father have been fighting with Grand Fisher? Grand Fisher laughed at Kurosaki's small sword, and Kurosaki's explained that they can compress (or something) their power into smaller weapons.
